Predicting a realistic target yield is one of the critical problems in precision farming. An artificial neural network was employed to model the nonlinear relationship between cotton yield and the factors influencing yield. Using sixyear field data obtained from LuoYang Dry Land Research Center, the neural network model was developed and trained, and the RMSE for test data was 3.70%. The result...

the concept of mathematical proof has been controversial for the past few decades. different philosophers have offered different theories about the nature of mathematical proof, among which theories presented by lakatos and hersh have had significant similarities and differences with each other. it seems that a comparison and critical review of these two theories will lead to a better understan...

In ostrich farming, gastric diseases are usual causes of increased mortality and economic losses. Infectious and non-infectious pathogens can damage the gastrointestinal tract, affecting the digestive process. Gastric impaction may be characterized by anorexia, cachexia, dehydration, apathy, decubitus, and dry and reduced feces. Chronic anorexia result in progressive loss on the reproductive pe...

The variation of forest types across Virginia reflects the diverse physiography of the state. From the sandy, low-elevation soils of the Coastal Plain to the dry, rocky soils on the southwestern slopes of the Appalachian Mountains, Virginia has one of the most diverse landscapes in the East (Fleming et al. 2006). Most forests in this area have been heavily influenced by anthropogenic disturbanc...

i Summary/Zusammenfassung ii Summary Evaluation of dual purpose cowpea varieties for dry season feeding of ruminant animals Cowpea is of major importance to the livelihoods of millions of people in the tropics. Resource-poor smallholder farmers derive food, animal feed, cash and manure from the crop. Dual purpose cowpea has the potential to function as a key integrating factor in intensifying s...

Caring and humanism in hospitals exist on both the organizational and the individual levels. This paper identifies key organizations and foundations that have succeeded in promoting or fostering caring environments in hospitals. These include the Picker Institute, the Baptist Healing Trust, Sage Consulting, and the Caritas Consortium. Exemplary, caring clinicians in hospitals are also described...

osmotic stress is one of the major factors that significantly reduce yields in dry areas. plants respond to this abiotic stress at physiological and molecular levels. many genes are induced under stress conditions by transcription factors. dehydration responsive element binding (dreb) protein is a subfamily of ap2/erf transcription factors which control expression of many osmotic stress-inducib...
